Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474398, here are decompositions:

41 + 31474357 = 31474398
47 + 31474351 = 31474398
79 + 31474319 = 31474398
97 + 31474301 = 31474398
107 + 31474291 = 31474398
149 + 31474249 = 31474398
181 + 31474217 = 31474398
227 + 31474171 = 31474398

Showing the first eight; more decompositions exist.
